TO ALL WHOM IT MAY CONGERN:

` Be it known that I, JOHN PEACE, of Camden, in the county of'Camden, and State of New Jersey, have invented a new and improved Machine for Bending Skelp for Tubing; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the,*accompanyingV drawings, forming part of this specification, in which- Figure 1 is 4a side elevation of the skelp-bending machine.

Figure 2 is a plan of the same.`

Figure 3 is a vertical section taken in thelinex x, between the clamping dies, ig.,1. i

Figure 4 is a front View ofthe clamping dies. i Y

This invention relates to the manufacture of metal pipes, or line-tubes, and consists in an arrangement of dies for` clamping and bending the skelp or iron plate into-shape, preparatory to welding the edges or laps so formed for making the tubes or iiues. The advantage of the machine, over machines in use for the saine purpose, is that the iat skclp or strip of iron` can be drawn out of the heating furnace in a fiat or horizontal position, thus avoiding the necessity, attending all other machines, of turning the metal plate edgewise, and thus `giving a twist o1' wind in the tivo edges to be welded. The simplicity of the machine saves much expense in its construction, with a continued saving oi" labor in its operation. v,

A represents a slide-rest, with supports or legsB B, to fasten it to a draw-bencl1. Fitted upon the sliderest A, is al1-adjustable bracket and lever fulcrurn, C, which is keyed at a a to the under side of the rest. At the opposite end of the slide-rest A is an adjustable stop, D, also keyed to the rest at b. A'bent lever, E, is pivoted to the bracket C, at c, and connected by the jointed arm Gr to one of a pair of` clamp dies, F F, which are made to t and move upon the sliderest A. The dies F F are made hollow and bell-mouthed on one end, as shown in Egt-4, of the properwidth for receiving the skelp flat when introduced into them, and tapering smaller to the opposite end until they assume nearly a half oval shape when closed. Two plates or pins, g g, are fastened iiush to the inner faces of the dies,one on each, and project down between them to form grooves for' receiving the edges'of the skelp which makes the laps for welding .and forming tubes. The adjustable stop vD moves upon the slide-rest A for the purpose of adapting it to dies of different sizes; and the adjustable bracket C, and bent lever E, are for opening and closing the diesF F. `The Hat sheet of iron orskelp is heated to ared heat in a proper heating furnace; one end is then placed with a pair of tongs between the dies in -the bell` mouthed end, so as to extend far enough through the other side for4 seizing it with a pair of pliers, when the lever E closes the dies and brings the skelp to its proper shape between them. The pliers which have hold of the skelp arethen hooked to an endless chain or draw-bench, which draws it through the dies and makes it the proper shape from end to end.

' Having described the construction and operation of my invention, what I claim as new, and desireto secure by Letters Patent, is j I cla-im the horizontal slide-rest A, or its equivalent, the adjustable bracket C, the bent lever E, the adjustable stop D, and the dies F F, all constructed,combined, andarrangcd substantially as and for the purposes herein described. j

' JOHN PEACE.
